Black Holes
A black hole is a region of space that has so much mass concentrated in it that there is no way for a nearby object to escape its gravitational pull. An example of gravity I will quote from Black Holes FAQ by Ted Bunn. "Suppose that you are standing on the surface of a planet. You throw a rock straight up into the air. Assuming you don't throw it too hard, it will rise for a while, but eventually the acceleration due to the planet's gravity will make it start to fall down again. If you threw the rock hard enough, though, you could make it escape the planet's gravity entirely. It would keep on rising forever." The speed with which you need to throw the rock in order that it escapes the planet's gravity is called escape velocity. The escape velocity all depends on the mass of the planet. If a planet's mass is big, its gravity is very strong, and the escape velocity is high. A planet of smaller mass, however would have a smaller gravitational pull and a lower escape ve!locity. Also the escape velocity also depends on how far you are from the planet's center, the closer, the higher. The Earth's escape velocity is 25,000 M.P.H. and the Moon's is 5,300 M.P.H.
Outside the event horizon there is still a gravitational pull, but it is not as strong as it is inside the horizon. Still nobody knows what happens when you go through a black hole, since no information can be sent back out. The event horizon basically marks out the boundary of the black hole. Instead of sucking up all matter that came within its event horizon like black holes, white holes spits out material. The energy that produces the radiation comes from the mass of the black hole. Once in the horizon no one can see you from the outside, since no light from you can't escape past the horizon. A black hole is created when a massive star runs out of fuel, at this point it is unable to support itself against its own gravitational pull and it should collapse on itself to create a black hole. (Singularity is a pointing the black hole where all matter is compacted to subatomic sizes) The effect would be you go through a black hole and come out a white hole. You'd have to look at the things around the area you thought was a black hole. The wormhole would take you to a different place in a different time. If stars, dust, and other things were orbiting around some "black" space, you could make a pretty good guess a black hole was there. Black holes have something, which is called the event horizon. with such an enormous intensity of mass in such a small area that its escape velocity is greater than the velocity of light. What is a Wormhole? A wormhole is a black hole with no singularity.
